The Biudrone 32 4230 70A ESC is the ultimate choice for builders prioritizing maximum power delivery and thermal headroom in their 5-inch, 6-inch, 7-inch, or larger FPV drones using the 30.5mm stack standard. Its heavy-duty construction ensures reliability under extreme loads.
Key Features:
- Extreme Current Handling: Provides a formidable 70A continuous current (75A peak) per motor, ready for the most demanding motor and prop combinations. Supports a wide 2S-8S LiPo input voltage range.
- Efficient Core Processing: Utilizes the capable AT32F421 MCU running at 128MHz for smooth, responsive motor control.
- Premium Component Selection: Employs imported Japanese MOSFETs for reliability, dependable FD6288Q gate drivers, and high-quality Murata capacitors for clean power delivery.
- Superior Thermal Design: Engineered with a 6-layer PCB featuring exceptionally thick 3oz copper, drastically improving heat dissipation and current handling capacity compared to standard ESCs. Includes a high-end resin plug hole manufacturing process and metallized edge wrapping on solder pads to prevent lifting.
- BLHeli_32 Compatibility: Ready for BLHeli_32 firmware (inferred) and supports all key ESC protocols up to DShot600, ensuring compatibility and precise control. (Note: Uses HAKRC_AT4G_Multi_32.9 Hex firmware target).
- Accurate Telemetry: Features an integrated current sensor (Galvanometer) with a scale ratio of 160 for accurate current monitoring via your flight controller.
